Power Steering Conversion Kit: Chev BB & SB V8 mostIf your manual non power assisted LHD Vehicles fitted with a Big Block or Small Block V8.. its begining of a easier way.. consider the option we get asked for from time to time. The steering box is a LHS mounted 4 bolt mount.. of which normally 3 bolt are used. NOT for 55 64 Chevrolet or 58 64 Pontiac Laurentian Parisisenne. The kit works best with the Chevy V8 but the frame on some cars may have a drilled alternative to this most common box bolt
